摘要： A printer of the dot matrix type has a series of hammers with pins that print on an underlying medium. The pins are released from magnetic retention by reversing the plurality of a permanent magnet. This is controlled by electro-mechanical drive circuits and logic circuits. The printer has a power supply which supplies an output of a voltage level for driving the electro-mechanical circuits connected to a ribbon drive, platen drive, paper feed, shuttle motor, and fans at a given voltage and the hammers at a different voltage. A thermal sensor is connected to a heat sink for power supply and the printer controller changes the rate of print when pre-established temperatures are sent.

摘要： A printer with a reciprocally moving hammerbank with a plurality of hammers thereon is disclosed including a magnet for retaining hammers on the hammerbank of the printer from a firing position. A coil overcomes the magnetism of the magnet by a circuit for reversing the magnetic field. At least a portion of the circuit comprises transistor drivers located directly on the hammerbank of the printer.
